Rio-C Drinking Water System is the newest addition to our inventory. At home or in the office, it's very convenient for you to draw a glass of sparkling, cold water any time you wish. Not only can you have great tasting, cold, water but you can also enjoy a cup of tea in the morning and a cup of soup at noon. And you can adjust the temperature of both the hot and cold water. The Rio-C utilizes a Direct Chill Coil (DCC) which keeps water chilled without an open storage tank providing better sanitation. This model also uses a unique stainless steel hot tank with a capacity of 1.5 liters. This stainless steel tank keeps the water at its hottest and provides you with unusually fast temperature recovery.
